OK I could not resist getting at least one V1800 set up and tuned up. Excuse the rushed phone pic. I ran a few movie scenes and then a few initial songs. Nothing very critical yet. A few things, it does sound tighter down low compared to my PC-Ultra, not sure if that is the difference of down firing corner loaded vs front firing ported in additional to the bigger driver working so little.
I ran a quick 6 position Audyssey and noticed as expected due to the size of this driver I had to have the gain almost at zero and still Audyessy set sub to -11.5db. I think I should get some 12db attenuators as from what I have read they wind up being closer to 6db anyway.
Next and getting the duals set up will help this I hope, but the sweet spot has moved it seems. My PC-Ultra was in same exact spot and my seating is about 13-14 feet in front of right speaker. While the bass is good there if you to the left directly in the front line of the sub the gain is huge (you feel it in your chest) and also a bit boomy, very surprising as the sub is pointed directly into that left sofa and it was not that much with the Ultra in same position. I was thinking of leaving them ion the corners, but now surely want to bring them next to the credenza and push the R/L fronts further apart.
I could not resist running the Edge of Tomorrow opening and the V1800 handled it very well, I did hear the driver flutter, but that is likely just the 10Hz sound of the driver. It never dropped/rolled off so bad I could not hear it, but it was likely not very clean. Other scenes felt richer and seemed to have more depth.
I will spend more time this weekend with it, running it through more paces movies and music. This thing is a beast, thank goodness for furniture super sliders ;-)
